GQCA0227R4GT

GQCA0227R4GT Description

The GQCA0227R4GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 27.4Ω resistance and a tight 2% tolerance, ensuring consistent performance in precision circuits. The ceramic case and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is engineered for low-noise, high-reliability environments.
